DISK-HARROW BOXING.

mcoaar.

To all whom it may concern Be it known that I, JORGEN A. REIMER, a-

citizen of Denmark, residing at Elk Horn, -in the county of Shelby and State of Iowa, have invented certain new and useful Improvements in Disk-Harrow Boxings, of which the following is a specification.

The present invention relates to improvements 1n journal boxes especially adapted for disk harrows, the object of my invention being to provide a simple dust-proof construction embodying means for adjusting the journal bushings to take up wear, and means for holding said bushings relatively stationary'with respect to the journal member.

With the above and other objects in view, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:

Figure 1 is a rear view of a disk harrow construction of conventional form and showing generally the application of an embodiment of my invention. Fig. 2 is a horizontal sectional view through my device. Fig. 3 is a vertical sectional view, parts being broken away and shown in section and other parts in elevation to more clearly bring out the details of construction. Fig. 4 is a transverse sectional view.

Throughout the following detail description, and on the several figures of the drawreference characters.

It will be apparent to those skilled in the art to which this invention refers that the journal boX forming the subject matter thereof is capable of being applied not only to a harrow construction of the type herein illustrated, but to other mechanisms Where rotatable supporting elements are utilized. I, therefore, do not wish to be confined to its adaptation to a disk harrow alone as herein described.

In Fig. 1 of the drawing, is illustrated conventionally a disk harrow embodying a disk supporting shaft or shafts indicated 1,

50 the disks 2 arranged in spaced relation thereupon and journal boxes?) connected to draft means 4 at their forward end and to the harrow frame 5 by means of hangers or supporting standards 6. His the detail construction of the journal box with which this invention has to do, and said device comings, similar parts are referred to by like Specification of Letters Patent. Pate t d N 16 1915 Application filed June 11, 1915.

Serial No. 33,521.

prises .a substantially cylindrical hollow body member 7, the ends of which are externally threaded as indicated at 8. Within the box or body member '7 is rotatably mounted the bearing member 9 which extends longitudinally of the body 7 and is formed at one end with an enlargement or head 10 adapted to abut against the annular inner shoulder 11 formed at one end of said body member 7. The reduced portion of the bearing member 9 is threaded at its other end to receive a locking member or nut 12, conforming substantially in configuration and construction to the enlarged head 10 hereinbefore mentioned. Both the bearin member 9 and the nut 12 have square shape openings therethrough to receive a similarly shaped shaft 13 on which the disks of the harrow construction are adapted to be received for rotation with said shaft. Obviously the bearing member 9revolves with the shaft 13 when the harrow is operated in the customary manner.

The nut 12 is designed to seat against the.

nut is interposed a bushing longitudinally divided to form the upper section 14 and the lower section 15 most distinctly disclosed by Fig. 4 of the drawing. The bushing consists preferably, as customary, of wood material or obviously it may be of any other characteristic material for performing the function of this construction.

On reference to Fig. 4:, it will be observed that the lower bushing section 15 is longitu' dinally grooved to receive the projection or rib 16 formed on the inner wall of the body 7, such projection locking the bushing section against tendency to rotate. The upper section 14 is substantially of a similar form, but whereas the section 15 is semicircular in formation exteriorly, the said upper section is many sided. As also noted in Fig. 4, the sections are disposed in such a position that the longitudinal division is at an angle to the horizontal, substantially at about 45 and the purpose of this disposition is to insure that the wear and tear will be practically wholly received by the upper bushing section 14 at a point which would lie between the plane of draft of the harrow and the vertical plane of the weight carried by the journal box. It, therefore, followsthat only one of the bushing sections will necessarily have to be renewed from time to time,

whereas in usual journal boxes of this charaoter both sections are customarily positioned to receive the wear.- e

y reason of the form or shape of the upper bushing section 11, the tendency to rotate is practically prevented but said section, furthermore, is provided with a recessed seat in which is positioned a plate 17 against which an adjusting bolt 18 impinges. This .bolt prevents entirely likelihood of the bushing section rotating in the box and being mutilated, and, furthermore, since said bushing sections are arranged in spaced relation, provides means for taking up the wear betweenthe parts. The bolt 18 is preferably provided with a lock nut 19 to hold it at adjusted positions. It will be obvious that only a single adjusting member of this character may be employed but for the purpose of convenience and otherwise, I employ two such adjusting elements as disclosed particularly in Fig. 3.

-At each end of the journal box hereinbefore described, is a dust cap 20 of similar constructions, and said cap is designed to hold packing material which may be seated upon the head 10 and the nut 12, thereby very adequately protecting the bearing against dust and grit which in devices of this character is a very essential feature.

Toprovide' for adequate lubrication of the hearing, I employ a grease cup 21 communicating with a passage 20 which leads to the space between the bushing sections 14, 15. The box is formed with an offstandingapertured projection 23, to which the hangers 6 of the burrow frame are secured. At the forward portion of the box, it is suitably fdrmed with a vertical opening 24 to receive a pivot bolt 25 with which the yoke 26 is connected adjacent to its ends and with which also the draw bar 27 connects at its intermediate portion, said draw bar passing through a slot 28 in the yoke member. This draft connection prevents movement of the journal box on the disk axle and incidental likelihood of breakage of the connection between the hangers 6 and the projections 23.

With the foregoing in view, it will be apparent that a very simple construction is provided and one which is capable of being easily dismantled for renewal of parts or other repair purposes.

Having thus described my what I claim as new is:

1. A journal box for harrows consisting of a body, a shaft bearing rotatable therein, means holding said bearing in the box, a bushing intermediate the bearing and the box, and means for holding the bushing relatively stationary, said means constituting adjusting means for taking up of wear of the bushing.

invention,

2. A journal box for harrows consisting of a body, a shaft bearing rotatable therein, means holding said bearin-g in the box, a longitudinally divided bushing intermediate the bearing and the box, the bushing sections being arranged in spacedrelation, and means carried by the box and cooperating with one of said sections to adjust the bushing and hold-said bushing against rotative movement.

3. A journal box for harrows consisting of a hollow body, a shaft bearing extending through the box and rotatable therein and comprising an enlarged end engageable with one end of the box, and a locking member having threaded engagement with the bearing and engaging the box at the other end.

4. In combination a. rotatable shaft, a journal box therefor, a. bearing member in the box interlocked for rotation with the shaft and comprising an enlarged head at one end adapted to abut against the box at its corresponding end, a locking nut having threaded connection with the bearing member and adapted to engage the box at the other end, a bushing disposed on said bearing between the enlarged head and the locking nut aforesaid, adjusting means carried by the box for taking up wear of the bush ing, and dust protecting members having threaded connection with the box at its end.

5. In combination a rotatable shaft, a journal box therefor, a bearin member in said box interlocked for rotation with the shaft and comprising an enlarged head at one end, a locking nut securing the bearing member in said box, a bushing intermediate the locking nut and the enlarged head aforesaid, said bushing comprising spaced sections, one of said sections having locking means for preventing rotative movement thereof, and adjusting members carried by the box and cooperating with the other bushing section.

6. In combination, a rotatable shaft, a journal box therefor, a bearing member in said box interlocked for rotation with the shaft and comprising an enlarged head at one end, a locking nut securing the bearing member in said box, a bushing intermediate the locking nut and the enlarged head aforesaid, said bushin comprising spaced sections, one of saiif sections having locking means for preventing rotative movement thereof, adjusting members carried by the box and cooperating with the other bushing section, a plate member carried by the lastmentioned section against which the adjusting means is seated, and lubricating means carried by the box and communicating with the space between the bushing sections.

In testimony whereof I affix my signature.
